LIQUID DISPENSING APPLICATOR Filed Aug. 2l, 1935 @f @af/- Patented Apr. 14, 1936 UNITED. STATES PATENT OFFICE 4 Claims.

'I'his invention relates to improvements in applicators for dispensing liquid from containers. More particularly, my invention provides an inexpensive cap for a glass jar or other container such as those in which pharmaceutical and medicinal products are packaged and sold in the mar- 'ket, which container-closing cap means is oombined with dispensing and applying means for the liquid contents, the container being used as a handle. The principal utility of my invention is for a structure for applying pharmaceutical or medicinal products such as liniment, alcohol, and others which are usually applied externally to the skin, which products must necessarily and desirably be deposited and applied to the skin surface in limited and substantially evenly distributed quantity, or, in the case of certain products, to be rubbed into the skin or other 'absorbing surface. While the foregoing sets forth the principal uses, I desire that it be understood that my device may also serve as a regulatory selffeeding device for the application of various liquids and for various purposes.

It is an object of my invention to provide a combined container-closure cap and restricted nozzle which are preferably formed integrally and the interiors of which communicate with each other and wherein the nozzle terminates in a restricted slotted opening which is normally obstructed by a block of porous material which permits restricted ow of liquid therethrough.

A further object of my invention is the provision of a combined screw threaded containerclosure cap and communicating outlet nozzle which terminates in a relatively long but narrow opening which opening is positioned substantially diametrically with reference to the container cap and which has removable, yieldable, porous and renewable means disposed over said opening to restrict and evenly distribute the out-flowing liquid, in combination with a removable hood or cap which frictionally and releasably engages the outer` portions of the nozzle per se.

A further object of my invention is the provision of a combined metal cap and nozzle having a relatively long narrow nozzle opening and having integrally formed opposed flanges above and adjacent said opening adapted to releasably hold a block or section of porous brous material which is adapted to restrict-and evenly distribute the outowing liquid.

Other and further objects of my invention will be apparent from the following description and claims.

This invention, in (a preferred form) is illustrated and described in the following specification and claims.

Fig. l is a perspective view of my nozzle liquid applicator with the metal hood shown in raised position.

5 Fig. 2 is a top plane View showing the liquid applicator and nozzle opening from above.

Fig. 3 is a cross sectional view of my liquid applicator taken on line 3-3 of Fig. 2.

Fig. 4 is an elevational view of the disk or sealing ring which is insertable into the closure cap of my invention for effecting proper seal.

Referring to the drawing, reference numeral IIl indicates a container or jar of glass or other suitable material such as is used in the packaging of pharmaceutical or medicinal products. Said container I0; while illustrated in the preferred form I of the drawing as circular in cros's section, may be of any other known shape and size within a limit for convenient handling and gripping by a persons hand. Reference numeral II indicates an annular metal cap which in shape and size is substantially like screw type caps of conventional construction, said cap II having perpendicularly and downwardly extending annular flange I2 which is suitably spirally grooved to form-screw thread I3, as clearly shown in the cross sectional drawing of Fig. 3, said screw threaded flange I2 being adapted to threadingly engage corresponding external threads formed adjacent the upper periphery of the jar or container I0.

Screw cap I2 has a relatively large central aperture I4 formed therein which forms an outlet port for the container liquid contents when the container is tilted or inverted. A sealing ring I5 l of cardboard or other fibrous moistureimpervious material is preferably inserted to fit snugly in screw cap I2 in order that said screw cap will form a liquid tight seal on the container I0, said sealing ring I5 setting on the upper periphery of the container and being impinged therebetween and said screw cap. As indicated in Fig. 3, after the purchaser of the applicator and contents purchases same and desires to apply the liquid contents such as liniment or the like, he may either perforate the sealing ring I5 along perforated circular area as indicated by reference numeral I5a to form an aperture in register with aperture I4, or said sealing ring may be entirely removed and the screw cap and applicator device reassembled.

Securely mounted on the upper surface of screw cap I2 is a metal nozzle I6 which although shown of rectangular shape, may assume various shapes, widths or lengths. In the preferred form nozzle I6 is preferably formed from a single metal blank which is suitably slit and bent to form a a substantially rectangular box-like structure as clearly shown in Figs. 1 and 3 and wherein the upper portion of the relatively longer opposite sides and I8 respectively are bent along a horizontal i line and diagonally toward each other until they vare relatively near each other to form a relatively narrow elongated opening I9 as clearly indicated at the top of Fig. 3. 'I'he edges of the shorter end members are secured by welding or the like to adjacent edges of nozzles side walls I1 and I8. When the converged sides of the opposite walls I1 and I8 have been formed to leave relatively nar-A row opening I9, each of said sides is bentr at an obtuse angle and outwardly from each other and the ends thereof are thence bent toward each other to form oppositely facing spaced apart concave flanges 20 and 2| respectively, the upper edges of said flanges terminating a short distance apart along their entire length as clearly indicated in Fig. 1.

A section or block of cotton or wool felt 22 (which may also be of other pervious fibrous material) is inserted between opposite anges 20 and 2| wherein said felt block 22 is impinged but removable. Said felt block 22 extends from one end of said iianges 20 and 2| to the other end and acts to partially obstruct and regulate the flow of liquid through nozzle opening I5. It is apparent that upon tilting or inversion of the applicator, that the liquid contents will contact and soak into felt block 22 and be thereby substantially evenly distributed along the entire width of opening I9 and felt block 22 and also beregulated to an even flow so that the proper and desired amount of liquid will have been applied. It is to be noted that a portion of the felt block 22, because of its yieldable and spongy body, extends above anges 20 and 2|, this providing means whereby the inverted applicator and particularly the felt block 22 may be rubbed along the surface to which the liquid is to be applied resulting in relatively thin application of the liquid contents.

As important uses of the applicator are designed in the field of manual application of medicinal and pharmaceutical products wherein maintenance of cleanliness is important, I have provided a substantially rectangular and cubical hood or cover 23 of relatively thin metal, as shown in Fig. 1. The size of the cover 23 is such that it will snugly fit about the 4 sides of the nozzle I6 to thereby enclose the felt block 22 and maintain it free from exposure to air and dust.

I am aware that numerous details of the construction of my invention may be varied through a wide range without departing from the principles of my invention, and I therefore do not desire to limit my patent to the particular or preferred form illustrated.

I claim as my invention:

-2. A dispensing applicator for a liquid container comprising a main cap body adapted to be releasably secured over the mouth of a container, a portion of the sides of said container; a substantially rectangular upwardly extending tubular nozzle secured on said cap body, said cap body having a central aperture to form an outlet port to interior of said nozzle, two of the opposite walls of said nozzle extending first vertically and then converging diametrically toward each other to form a relatively narrow opening and thence at the point of said opening each being bent diametrically and away from each other and the upper edges of said sides being bent toward each other to form a relatively narrow elongated chamber, and a block of relatively narrow yieldable and expansible brous liquid absorbent material removably mounted in said nozzle chamber and upon said nozzle opening.
